Sure. And a sex offender could be a cab driver too. Or a teacher. Or whatever. The prevailing argument against any new service business these days seems to be “but what about the sex offenders??” As conservatives, we should be concerned about why a business IS a viable idea, and not looking for the one in a million reason that it might not be. In my opinion its the liberals who are always trying to shoot down the new ideas.
I would want the Uber driver to disclose whether he is a sex offender. Even Libertarians support warnings.
